HMMM! I just came across something interesting here: MSIHardware.com a site unknown to me has a file available for download entitled audigyxp.zip @ 14.3mb download size. The file was uploaded today and FDRSoft reports these drivers sport a version number of 4.12.01.0130-1.20.0030 (as well as these drivers work for all Windows OS) while the original files from CD are 4.12.01.0125-1.00.0010. I found nothing on Creative's pages about these new drivers. Download @ your own risk Leave your comments on these drivers here or in our forums.
Update by Degger*: Link is fixed and @ the moment we are uploading the file to our server!
Stay tuned!
